My roomies called their cousins 'double cousins' and they looked very similar. They wouldn't be siblings because they had different parents. But the "Smith" twin girls married the "Jones" twin boys.
Technically, they do have different parents, but in the genetic world, if identical twins marry identical twins, then genetically speaking, all the kids would have the same genetic makeup.
Now that would be confusing.
